I am buying a gsr soon and i live in Cali, the gas rates are 87 89 91, is it ok if i use 87 or 89 here? i livei n the bay area, anyone heard of any problems? The engine is stock except for exhaust short ram intake and suspensions Will any problems occur if i use 89 w/ a b18c1 block?"

 

I would not use anything less than 91-92+. You will get the best mileage and performance from the higher octanes. Although the B18c has a knock sensor, it will pull timing to compensate. Especially under a heavy load.

 

i read somewhere that ppl say their cars run fine on 89 but i aint sure, more answers please. I seem to know some people who mix 89 and 91 together or run 91 till empty and fill 89 then switch back off to 91 when 89 is empty"

 

People say 91 but i might try 89 and see if it runs smooth, is 3-4 gallons of 89 from empty good enough to test it? If it turns out it bogs like **** after then i can wait a shorter time limit to empty it then use 91 again, well any answer would be helpful

i know for sure a lot of ppl say it bogs on 87

 

Use 91 or get an LS.

agreed

Sometimes i wonder what the middle (89) is for I never actually heard of anyone use it, it's 87 OR 91 only (feels like a noob for not knowing what 89 is for )

 

Really all the people bishing about the difference between 91 and 87 or 81 are just stupid. The difference between 91 and whatever the lowest grade is most likly only 20 maybe 30 cents per gallon. The car holds..13 gallons do the math.

Its not much cash difference so just suck it up and get 91 if you have a gsr =/

 

I use 89 and there is absolutely nothing wrong with mine, I'm thinking about going to 93 the highest octane here after 89

 

Why not use what the owners manual/the people who spent millions researching and making the car recommend?

If you cannot spare the under five cents a litre difference you shouldn't buy a car.

My thoughts exactly.

 

i wouldn't even touch anything that is lower than 91. trust me. i know this might sound stoopid but i accidently put 89 in my car once. thing boggs like a ****.

 

I've used 89 several times cause the gas stations didn't have 91, and my car never bogged or pinged, the 91 octane is recommended for better performance and hp but your ecu will compensate for lower octane. But yeah, for another $2-3 per fill up, its worth getting the 91 octane.

The owner's manual recommends using premium fuel, pump octane 91 or higher. It says that lower octane fuel than that won't damage the car, but performance will be degraded.

Part of performance is fuel economy. You're probably going to get a few less miles per gallon on 87 or 89 octane fuel than with 91+, which more than offsets any cost savings for the lower grade fuel. Which means that if you think you're saving money by not getting premium, you're wrong.

Stick with premium fuel. If this is a problem for you, buy a different car.

if your going to cry about a $1.50 extra each time you shoud not buy the car. in my car run a minimum of 91

 

Ohh I love these threads.. When the dash says "Premium Fuel Only" Im assuming that you should probably use Premium... If your too cheap to get 91, dont buy a GSR..... Liek someone said, the difference is like under 2 bucks, If your that poor, you shouldnt be driving at all... walk.

 

my car says use only dot 3/4 brake fluid but im too cheap so i just put in water and it works fine.

Thats expletivein hillarious.


But....I NEVER run anything below 92 octane. Sometimes i even run 102 race fuel, but nothin below 92

 

b18c1 requires 91 octane, dont use any less 91 you will expletive up ur motor and your car will run like ****. if you want to run 87-89 octane get a ls integra

 

man, its like a 10 cent difference between 89 and 91. that's about $1.00 to $1.20 each time you fill up. Its not that much people.

and, if you use 91, you can advance your ignition timing a little bit and pick up some free hp.


edit: if you live in the bay area, you are going up/down a lot of hills (up hill = added load on the engine), so I'd think you would want to make sure you use 91 for added insurance against knocking

 

I don't think honda wouldve spent money on the sticker on the gas door that say "PREMIUM FUEL ONLY" if the car was ok with anything less IMO

 

I'll have to agree with that. I have a gsr and since day one, I've used 91 or 93, whichever is available. If the manual, and even the dash recommend that grade, then that's what I go by.

 

sunoco 93 octane does fine

 

i use 89 most of the time with myn n it runs great....but once in a every third fill up illl use 92 and theres no doubt it runs even better but iv never had any problems using 89
